In the 1920s, the richest people per capita in the world were members of the Osage Nation in Oklahoma, thanks to the oil that was discovered beneath their land. Then, one by one, the Osage began to die under mysterious circumstances, and anyone who tried to investigate met the same end. This youngification of the adult bestseller is a searing indictment of the callousness and prejudice toward Native Americans that allowed the murderers to continue for so long and provides essential information for young readers about a shameful period in our history.
